Ryan introduces the general integration guidelines in two practical scenarios: infrastructure-less and infrastructure-based IoT networks based on the aforementioned typical low-power wireless networking technologies, such as EnOcean, ZigBee, 6LoWPAN, LTE-M, and LoRaWAN, where the software protocol stack on the IoT devices and cloud service interfaces are discussed.
- [Instructor] We have seen the examples…of how to make…different networking technologies work together.…There are several typical integration options…we can consider.…The first option is integrating…two or more different LoWPANs together…so that we can have a ZigBee plus 6LoWPAN network,…an EnOcean plus ZigBee network,…or a Bluetooth low energy plus ZigBee network.…The second option is integrating different LoWPANs…and low power WANs together.…
For example, we can have a ZigBee plus LoRa network.…The third option is integrating…different low power WANs together.…For example, we can have a LoRa plus LTE-M network.…The last option is integrating LoWPANs…or low power WANs that connected…to a regular local area networks,…or wide area networks, into one network.…
For example, we can have a ZigBee plus Wi-Fi network,…a 6LoWPAN plus ethernet network…or a LoRa plus a GSM or 4G network.…In this case the router or gateway…needs to have low power wireless radio modules…and local area network or wide area network modules…with software in order to provide connectivity…
Ryan Hu begins by introducing wireless networking for IoT, and going over the basics of wireless communication and wireless networking. Next, he presents and compares the underlying wireless networking technologies in terms of system architectures, communication paradigms, performance, and use cases. Then, he explains how to integrate various networking technologies into an IoT system. To wrap up, Ryan discusses the use of low-power wireless networking in a typical lighting control system for both smart home and smart city environments.
